Senior at the International Academy here (a public high school in Michigan). One of my classes uses Google Classroom.

I think that Google truly took a "Google Plus" look and morphed that into a website for teachers. I love how it has a clean and easy to use UI. The assignments are on a side bar, announcements are clearly displayed in a "stream". You can easily post a message to your class, and you have access to everyone's email (making it easy to communicate).

Teachers in my school have used three platforms. Moodle, Google Classroom, and Edmodo. Quite frankly, I have come to like Edmodo much more. They're identical to Facebook, but the layout is so much better than the alternatives (in my preference). Edmodo has truly thought everything out.
